How we make steel | British Steel

Coke, iron ore, sinter and limestone are fed – or charged – into the top of the furnaces. A hot air blast of temperatures around 1,000°C is injected at the bottom of the furnace through nozzles called tuyeres. As the coke burns, temperatures higher than 2,000°C are reached and this heat creates molten metal (iron).
